The Charwoman's Shadow (Ballantine Adult Fantasy Series)

An old woman who spends her days scrubbing the floors might be an unlikely damsel in distress, but Lord Dunsany proves once again his mastery of the fantastical. The Charwoman's Shadow is a beautiful tale of a sorcerer's apprentice who discovers his master's nefarious usage of stolen shadows, and vows to save the charwoman from her slavery.
